JAMES TRAVILLA, .IRtLQE'y UNIVERSITY CITY, MISSOURI, ASSIGNOR TO GENERAL- STEEL. k"H'lLS'lINGI- S CORP{BRATOJQ OF GRANTE CITY, (ILLINOIS, AKCORPORATIONT 0I DELAWARE RAILWAY ROLLING STOCK CONSTRUCTION Application. meanecember 26, 1929.

My linvention relates to railway rolling stock and' lconsists in a novel spring equalizing system for supporting a vehicle frame from vehicle axles and in novel frame and journal box structure particularly adapted for the system.

have developedmy arrangement particularly for use in the spring equalizing system of a locomotive. l

It has been the common practice in such structures to mount journalboxes on the driver axles, mount leaf springs on top of the journal' boxes, suspendV links' from the adjacent ends ofthe springs and support equaliz-V ers therefrom, connecting' 'the ends of the equalizers to the lovver ends of the links and' pivoting the. intermediate portion of the equalizers on the locomotive frame'. j

j 's arrangement requiresthe upper'portionjof the locomotive frame above the pedestall openings'to be constructed so as to accommodate the spring saddles and the ecpializei1` suspending links g' and locates the springs either above' the side members of the frame or, if the side members are hollow, between the' vertical Walls of the side members, the side members oi the llatter type having large openings in the top for insertion 'of the spring, This construction, therefore, makes it very diliicult, in view ofthe necessary Clearance conditions for the various parts' of spring rigging and undertrame,l tol obtain the desired cross sectional area and contour of sideirame members above the pedestal The' main objects of my invention are to locate the springs below the main'side mem'- bers ofthe frame and to eliminate provision forthe accommodation of spring saddles and V framejmem'ber as referred to',

to be easily removable `and to4 eliminate the Y hangers cutting into the Walls of thefunderframe. Y Y Another object .of my invention fis to re'- duce the' number or" parts of the spring equalizing system and simplify they construction by utilizing the journal boxes themselves as equalizer elements of the spring system.

iiioth'er object or" my invention is to probe detailed Serial N o. 416,628.

vide the journal box With thimbles at the bottom of the box to increase the strength and act as spacers and prevent the box from closing inand binding the cellars.

Another object of'my invention is to pivot the journal boxes on the axles, thereby eliminating' much of the binding' action which results from the verticalv movement of boxes in their pedestals in the ordinary equalizing systems in which the boxes have sliding movement only.

Another object Of'my invention is toeliminate pedestal application and vremoval" of boxes, springs and drivers; and'to eliminate the machining of the pedestal binders and toes.

A further object of my invention is to sim'- pliiy, and thereby improve the appearance,` increasel the strength and, at the same time, lighten and otherwise improve the frame structure which is made possible by providing for better distribution of the metal as a result of the elimination of provision for passage therethrough of the springs, spring saddle, and equalizer supporting links.

These and other objects of my invention are attained in thel structure illustrated in the .accom anvin drawinvs in Which` P g vc Figure lis a top view of one longitudinal half of a locomotive frame arranged for my novel constuction.

A series of four drivers l, 2, 3, et is shown. each driver being mounted upon a corresponding axle 5, 6, 7, 8, respectively, and each axle mounting a journal box 9 Which rests upon the usual brass 10 carried by the axle and is arranged to tilt about the axle as will later.

Each box includesr projecting flanges or arms 11- from which linlrs 12 are suspended Y and the links on the adj aceiitianges of two i adjacent'boxe's pivotally shown) inthe usual manner.f-

i the portions mount the ends of leaf springs 13. The right hand end of the main system comprising the outerfliange 11a of the box on axle 8 is anchored to the frame by means of ashort link 14 andthe left hand supportsthe end of' end of the main system an equalizer l-which preferably is fulcrumed on the truck frame (not shown) and is connected` to the f truck spring system (not The main frame 1"( includes a side member 18 having a general box-like cross section and including pedestal jaws 19 andV depending elements 2O between said jaws resting on the springs 13. Preferably, and elements 20 are formed Vintegrally with the side member 18', the entire frame Vstructure consisting of a vone-piece casting, al-

`though this preferredconstructionisnot essential to theembodiment of my invention. In comparison with previous constructions,

the side members ,of my underfraine have a lgreater depth and uniformityk of section at above thepe'destal openings and therefore it is easier to'obtainthe necessary strength; and theradii at the top corners of the pedestal openings are larger so as to provide greater strength andeasier machining of thepedestals. .This construction is particu- Vlarly advantageous for three yor four cylinder Y locomotives in which the center crank and pistonl rod necessitate the elimination of the desirable framing intermediate the side i frames which is possible with a two cylinder locomotive.

f semi-circular brass in the. usual manner.

The box and-containerl bearing structure differs substantially in a number of respects from the usual driving box structure. The 10 is applied to each axle The box struc-turev rethis brass includes front and rear ceiving the longitudiwalls 22 and 23, respectively,

nal-extensions of which form the flanges or arms 11 previously referred to.

A cylindrical transverse wall 24 lextends between walls box and have concave'innersurfjaces fitting Y the exterior surface of the steel box and have 22 and 23. Blocks `or sleeves 25', preferably ofbrass, are applied to this portion ofthe straight outer surfaces engaging the pedestal jaws 19 or, preferably, .hardenedv steel liners 26. fitted over the pedestal'jaws and securedl vThis arrangement of brassv against steelreduce's lthe wearon-the surfaces of adjacent parts'.

theretoV bolts 28.

Transverse bolts 21 extend through;thef'pe'destal jaws and box flanges'll and j the'pedestals when the structureis being assembled or disassembled,'andto hold the box` through elongated vertical slots2-7 in the serve to hold the boxes in iny placeif the engine is to be lifted. The lower portions of the walls 22 and 23A on opposite sides of the axles Vare securely braced by spacers or thimbles 29 and bolts BO extending vallel sides and rigid bearing the pedestal jaws' tically in the pedestal openings in the usual manner. The constructionavoids the condivordinarybox.V withv parsupport in which the box, as a whole, tends'to tilt on the axle and stick inthe Vpedestal and the overcoming of which tendency results in undue and uneven wear on the sides of the box.

. It will be readily seen that the replacement of a springer a box, or an axle or an axle bearing, is eiected much morereadily than in the Vordinary ,construction where the springs and spring hangers Vare contained in part or in whole in the locomotive frame and are covered in whole or in part byvalve gearing or brackets, pumps,`etc.,v mounted on the frame. Th-e points of support of the frame are very low which provides increased stability. The frame constructionis strengthened (orequal strength can be obtained with less material) because ofthe elimination of the openings in the 'frame sary to accommodate the spring rigging and tion existing in the a substantial amount of machining on thev frame is eliminated. K I ,Y f

Obviously other variations may be made in my structure without departing from the spirit of` my invention and I contemplate the exclusive use ofl such modifications as come within the scope of my claims.
